Worcester Bosch Greenstar 8000 Life 30kW Combi Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar 8000 Life 30kW a combi, system or regular boiler?

You may wish to consider installing the Worcester Bosch Greenstar 8000 Life 30kW if you are looking for a combi boiler for your house or flat.

Combi boilers were introduced by manufacturers in the 1970s to offer British homeowners a way to cheaply and reliably heat their homes and have hot water without taking up too much space. Previously, most boilers had one or more storage tanks, which either heated water and kept it warm or held water to be heated later.

With combi boilers, there is no need to find space for large tanks around your home as the hot water needed for your radiators and taps is available on demand. Combi boilers do this by drawing water from your mains supply, heating it instantly whenever you need it and then distributing it to where it's needed in the home.

The major disadvantage to combi boilers is that they have a maximum capacity for heating water. In a larger household, water pressure, volume and temperature will drop if two or more people are trying to use hot water at the same time.

Is a Worcester Bosch Greenstar 8000 Life 30kW combi boiler appropriate for my house or apartment?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

Your boiler's output indicates the maximum amount of power available to it to heat the water you need to warm your radiators or when you want hot water from your taps. A higher output rate means that your boiler is capable of heating greater volumes of water.

If a boiler's output rate is too low, you'll often find that the water is not as hot as you want it to be. Too high, however, and you'll end up paying more for your gas than you should be.

The Worcester Bosch Greenstar 8000 Life 30kW combi boiler has an output rate of 30 kW, so which types of property would this be suitable for?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

If you are considering installing a combi boiler in your home, you need to consider the flow rate as well as the output rate.

The flow rate is the volume of water (measured in litres per minute) that your boiler can instantly heat up and send around the home. The more demand in your home for water at the same time (for example, two people taking showers in different bathrooms), the higher the flow rate you'll need.

However, the actual flow rate your boiler can deliver is also determined by your mains water pressure. If you choose a boiler with a flow rate of 16l/m but the mains water pressure is 12l/m, your boiler will only perform to 12l/m. This Worcester Bosch Greenstar 8000 Life 30kW Combi boiler's flow rate is 11 L/m.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


Dimensions of the Worcester Bosch Greenstar 8000 Life 30kW boiler

The Worcester Bosch Greenstar 8000 Life 30kW boiler is 825 mm high, 440 mm wide, and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life 30kW a non-condensing or condensing boiler?

We recommend that you select a condensing boiler like the Worcester Bosch Greenstar 8000 Life gas Worcester Bosch Greenstar 8000 Life 30kW for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

Is the Worcester Bosch Greenstar 8000 Life 30kW combi considered environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Would choosing the Worcester Bosch Greenstar 8000 Life 30kW combi be an environmentally-friendly choice? If so, let's look at its performance figures.

Boilers manufactured after April 2018 in the UK must achieve an "A" on the SEDBUK grading system as well as score a minimum of 92% on a separate energy efficiency test. Prior to that, the minimum was 88% - boilers rated at 88% and 89% were given a “B” rating (90% and higher were given an "A").

An energy efficiency rating describes how much energy the boiler uses and how much it wastes when in use.

The Worcester Bosch Greenstar 8000 Life 30kW was awarded an efficiency rating of 94% with a SEDBUK grading of "A".

The Energy Related Products (ERP) Directive is important European legislation that aims to limit energy use and harmful gas emissions during the manufacturing process, when the product is in use, and after it is disposed of.

For the Worcester Bosch Greenstar 8000 Life 30kW, the ERP Heat rating is "A" and the ERP Water rating is "A".

Am I covered if the Worcester Bosch Greenstar 8000 Life 30kW combi boiler breaks down?

The Worcester Bosch Greenstar 8000 Life 30kW is covered by a parts and labour warranty of 8 years following installation.

Worcester Bosch Greenstar 8000 Life 30kW Combi Gas boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar 8000 Life 30kW - system, regular or combi?

The Worcester Bosch Greenstar 8000 Life 30kW is a gas combi boiler.

Boilers traditionally required the installation of one or more large tanks around your property. These were filled with water that was either being heated or was to be heated later. British homes are among the smallest in the world so, to solve the space problem, manufacturers introduced combi boilers in the 1970s to offer homeowners the warmth and hot water supply they needed while taking up much less space.

A combi boiler is designed to heat both radiators and taps on demand and at the same time. Water from the mains passes through a combi boiler and the boiler's technology instantly turns it into hot water. Your boiler then distributes the hot water throughout your home.

The main disadvantage of combi boilers is that they have a maximum water volume capacity. What this means is that, if one person is using the shower while another uses a hot tap simultaneously, less water gets to each area, resulting in a fall in water pressure at both points.

Is a Worcester Bosch Greenstar 8000 Life 30kW combi boiler suitable for my house or flat?

You should make sure that the boiler you install in your property is the right "size". And size doesn't mean its physical dimensions, size means how much power it has - the "output".

Output measures in kilowatts how much power a boiler can use when heating water for your radiators or taps. The higher the output rate, the more water it can heat.

If the output rate is too low, your hot water might often be only lukewarm, and if it is too high, you will be paying more for your gas than you need to.

The Worcester Bosch Greenstar 8000 Life 30kW combi boiler has an output of 30 kW, so which types of property would it be most appropriate for?

An experienced boiler engineer would recommend that this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler would provide adequate heating and hot water for medium-sized homes and larger apartments with up to 10-15 radiators and two bathrooms.

As well as the output rate, you need to consider "flow rate" when choosing a combi boiler.

The flow rate describes how much water a combi boiler can draw from the mains, instantly heat, and then send to your radiators. Flow rates are measured in litres per second and this Worcester Bosch Greenstar 8000 Life 30kW Combi boiler's flow rate is 11 L/m.

The water in your mains pipe also has its own flow rate - normally between 10 and 12l/m in most parts of Britain. This means that, if you choose a combi boiler with a flow rate of 17l/m where local water pressure is 11lm, it won't actually process more water because of the slower flow rate of the mains.

In addition, larger households with more than one bathroom, multiple radiators, and where family members may want to use hot water at the same time (like morning showers) may actually need a boiler with a higher flow rate than either the boiler or the local mains pipe.

When our engineer comes out to quote you, they may recommend that you choose a heat only boiler or system boiler instead if your family's demand for hot water is higher than normal.


How big is the Worcester Bosch Greenstar 8000 Life 30kW?

The Worcester Bosch Greenstar 8000 Life 30kW stands at 825 mm tall, 440 mm wide and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life 30kW a non-condensing or condensing boiler?

We recommend that you choose a condensing boiler wherever possible like the Worcester Bosch Greenstar 8000 Life 30kW - try to go for the latest model, if possible, to take advantage of improving technology.

Condensing boilers capture and recycle the warmth still present in the water vapour condensation and in flue exhaust emissions created by burning gas to make them more efficient and economical to run.

You will save money on your gas bills too, plus condensing boilers are friendlier to the environment.

Is the Worcester Bosch Greenstar 8000 Life 30kW combi boiler rated as environmentally friendly?

Many homeowners are now worried about climate change and the damage they do to the environment from heating their homes has become a subject of increasing concern.

In the UK, central heating systems account for 14% of greenhouse gas production. Gas boilers in particular are responsible for emissions of dangerous nitrogen dioxide in British cities.

Do the figures suggest that installing the Worcester Bosch Greenstar 8000 Life 30kW combi at your property would help in the fight against climate change?

All boilers manufactured in the UK from April 2018 must achieve a SEDBUK “A” grade and an energy efficiency rating of 92% or above. Before that, the minimum was 88% - efficiency ratings of 88% and 89% were scored a “B” and 90%+ an "A".

A boiler's energy efficiency rating describes how much energy it uses and wastes during its standard operation.

The energy efficiency of the Worcester Bosch Greenstar 8000 Life 30kW was rated at 94% with a SEDBUK grading of "A".

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Worcester Bosch Greenstar 8000 Life 30kW is "A" for heat and "A" for hot water production.

Am I covered if my Worcester Bosch Greenstar 8000 Life 30kW combi boiler breaks down?

The Worcester Bosch Greenstar 8000 Life 30kW boiler comes with a parts and labour warranty of 8 years.
